Question 14 Tries remaining: 1 Marked out of 11.00 V Flag question In a study, temperature readings were taken at different locations in 1960 and in 2017. The average daily temperatures for the month of June in each of 41 different locations are listed below. We would like to see if there is any difference between the mean temperatures of 1960 and 2017. If you believe the populations are independent, then assume the population variances are equal.
